64693 divided by 72 
The aim is to understand the frequency of 72 in 64693.

Step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 72

Step 2:
72 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 72

Moving on to step 3:
When dividing 646 by 72, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 70 after subtracting 576 from 646.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 72

Step 4:
If we divide 709 by 72, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 89.0
Deduct 648 from 709 and we're left with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 72

Moving on to step 5:
If we divide 613 by 72, we get 8 and a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 898.0
The remainder is 37 after subtracting 576 from 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 6:
72 goes into 370 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 898.5
If we take 360 away from 370, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
72 can be fit into 100 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 898.51
If we subtract 72 from 100, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
If we divide 280 by 72, we get 3 and a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 898.513
Subtracting 216 from 280 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 898.5138
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
72 can be fit into 640 8 times, resulting in a remainder of 64.
The next digit of our result is 8. 
Result so far: 898.51388
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 898.51388, and the remainder is 6.4e-05.
